WebThe melting point changes from approximately 160 to above 300°C. on lowering the polymerization temperature from 125 to −80°C. X-ray diffraction studies show that polymers prepared at low temperature form crystals which have a substantial increase in perfection along the chain axis. WebThermal properties: Tg rigid PVC = 81 °C. Soft PVC has a Tg far below room temperature due to the plasticiser. Chemical resistance: Good resistance to UV radiation and sterilisation. Colour/surface Both rigid and soft PVC can be colourless and transparent with a shiny surface. PVC can be easily coloured. Processing
